To deploy quantum sensors for inertial navigation, at least two challenges must be resolved [1]}. First, the nature of cold atom interferometry is such that the resulting sample rate is typically below 10Hz. The lower the sample rate, the higher the achievable measurement accuracy [2]}, [3]}. This sample rate is significantly lower than existing classical accelerometers, which can operate at frequencies on the order of 800Hz. Second, the dynamic range of quantum accelerometers is very low, typically reported below e-2 [4]}, [5]}. Fundamentally, the output signal of a quantum accelerometer is sinusoidal, with the body acceleration value proportional to the signal phase. When the body acceleration value is beyond the dynamic range, the output signal will be wrapped because of the circular phase of the sinusoidal wave. In this paper we refer to this as the phase wrapping problem.
